US Sales Tax Calculator (by State) + Reverse
Enter a price and select your state to calculate the tax owed and the tax-inclusive total. Switch to Reverse mode to extract the original pre-tax price from a total that already includes sales tax. The 50-state base rate table is pre-loaded from 2025 figures — select a state to prefill the rate instantly, or enter any custom rate. Local and county rates are not included; always verify against your state's official source.
Base state rates only — local/county rates not included. Verify with your state's official revenue department. 2025 figures.

How it works
Forward mode is the common case: you know the pre-tax price and want the total. The calculator multiplies your price by the combined rate (state base rate, or any rate you enter) and adds the result. $100 at 7.25% yields $7.25 in tax and a $107.25 total. The rate you see in the dropdown is the statewide base rate only — most states allow counties and cities to layer additional local rates on top, which can add anywhere from zero to several percentage points. If you need a precise local rate, look it up from your state's revenue department and enter it in the rate field directly.
Reverse mode solves the non-obvious problem: you have a total that already includes tax and need to work backwards to the pre-tax price. The formula is preTax = taxInclusive ÷ (1 + rate). For example, a receipt showing $107.25 at a 7.25% rate means the item cost $100.00 before tax — you can verify: $100 × 1.0725 = $107.25. This operation is algebraically exact (no approximation), so the reverse result is precise to the cent for inputs that have two decimal places.
The state dropdown pre-loads 2025 statewide base sales-tax rates for all 50 US states. Five states — Alaska, Delaware, Montana, New Hampshire, and Oregon — have no statewide sales tax (rate = 0%), though some localities in Alaska do charge local sales tax. California has the highest statewide base rate at 7.25%. Rates are static reference data; always verify current rates with the official source for your jurisdiction before remitting tax.
Frequently asked questions
What is the difference between base rate and combined rate?+
The base rate is the statewide sales-tax rate set by the state legislature — the rates shown in the state dropdown here. The combined rate is what a buyer actually pays at the register, which adds county and city (local) rates on top of the base. In California, for example, the 7.25% base rate is the floor; many counties add 0.25–1% more, pushing the combined rate to 8–10.25%. This calculator uses the base rate when you select a state. For a precise combined rate in a specific city or county, consult your state's department of revenue.
Why is reverse calculation useful?+
When you receive a receipt, invoice, or quoted price that already embeds sales tax, reverse calculation lets you separate the base price from the tax. This is common in accounting (separating taxable revenue from tax collected), ecommerce (reconciling gross sales to net sales), and expense reporting (identifying the deductible base cost). The formula is simply preTax = total ÷ (1 + rate), which is algebraically exact — not an approximation.
Does this cover use tax, VAT, or excise tax?+
No. This calculator covers US point-of-sale sales tax only. Use tax (self-reported tax on out-of-state purchases) uses the same rate arithmetic but a different reporting obligation. VAT (used in most of Europe and over 160 countries) works differently at the legal level but the mathematics of reverse extraction are identical: price = VAT-inclusive ÷ (1 + VAT rate). Excise taxes on specific goods (fuel, tobacco, alcohol) are separate levies with their own per-unit or percentage structures and are not modeled here.
